Responsibilities

  • Design and build benchmark suites covering inference performance, model quality, and knowledge evaluation across hardware targets.

  • Strong C++ and Python experience in performance-sensitive contexts.
  • Solid understanding of inference fundamentals, including quantization, decoding strategies, and memory layout and their interactions.
  • Preferred experience porting models across runtimes and verifying numerical correctness.
  • Preferred experience working with external partners or clients in technical validation or evaluation.
  • Preferred familiarity with edge inference targets and their constraints.
